Despite our best hopes and struggle, Bernie Sanders’s presidential campaign once again ended in second place.

But while we came up short, it’s more than clear now that 2016 wasn’t a fluke — we do indeed have a mass constituency. And those Bernie supporters deserve a vehicle to advance their political project in the years to come — that means a formal organization capable of representing and galvanizing a mass movement. What form that organization should take, however, is up for debate.

Former senior Sanders 2020 campaign staffers will lead an effort called A Future to Believe In. This will be a large effort to inspire voters to support candidates such as Joe Biden. This new formation will not include some of the key social movement connections and volunteer-led opportunities that were the core of an “organizer-in-chief” presidential campaign. The Sanders world needs a new formation that will marshal distributed organizers, local grassroots leaders, national surrogates, and others to advance elements to continue the critical mass mobilizations harnessed by the campaign.
